Force logoff of ACTIVE players to curb "AFK-queue exploiting" is singlehandedly the most stupid thing I have read in 20 years of internet use.

Do NOT do this SE. Your login servers will prevent everyone with hour long queues, the AFKers log in and AFK again and this whole thing accomplishes nothing, except pissing off your PAYING customers who have a real life and limited time to play.

FIX your system (players can afk during crafting/retainer/cutscenes) and upgrade your server hardware.
THAT is the solution.
